Specifically, 'size'\nwill point to 'tmp' variable before the latter had a chance to be\nassigned any value.\n\nPlay it safe and init 'tmp' with 0, thus ensuring that\nradeon_vce_cs_reloc() will catch an early error in cases like these.\n\nFound by Linux Verification Center (linuxtesting.org) with static\nanalysis tool SVACE.\n\n(cherry picked from commit 2d52de55f9ee7aaee0e09ac443f77855989c6b68)\n\ud83d\udccf Published: 2025-04-03T07:18:59.933Z\n\ud83d\udccf Modified: 2025-04-03T07:18:59.933Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/78b07dada3f02f77762d0755a96d35f53b02be69\n2. https://git.kernel.org/stable/c/3ce08215cad55c10a6eeeb33d3583b6cfffe3ab8\n3. https://git.kernel.org/stable/c/dd1801aa01bba1760357f2a641346ae149686713\n4. https://git.kernel.org/stable/c/f5e049028124f755283f2c07e7a3708361ed1dc8\n5. https://git.kernel.org/stable/c/dd8689b52a24807c2d5ce0a17cb26dc87f75235c", "creation_timestamp": "2025-04-03T07:34:18.000000Z"}
